Abstract

Un sistema de impresión de alta velocidad que comprende: una platina que sustenta unos medios de registro: un portador que se desplaza hacia atrás y hacia delante a lo largo de la platina; un cabezal impresor que está provisto de una pluralidad de tipos y va montado sobre el portador; unos primeros medios para hacer girar el cabezal impresor, de manera que un tipo seleccionado entre todos ellos se desplace a una posición situada enfrente de la platina; unos segundos medios para golpear el cabezal impresor de manera que el tipo seleccionado impacte en la platina; unos terceros medios para controlar una intensidad variable de un impacto de impresión del tipo seleccionado a aplicar a la platina; y unos cuartos medios para espaciar el portador a lo largo de la platina; en el que los terceros medios actúan para proporcionar por lo menos una primera corriente excitadora y una segunda corriente excitadora sucesivamente a los segundos medios, teniendo la primera corriente excitadora una amplitud máxima de cresta constante con respecto a cualquiera de los tipos, mientras que la segunda corriente tiene una amplitud de cresta que es variable de conformidad con cada tipo seleccionado.
